Title: Respiratory mask having a rigid or semi-rigid, insert- molded filtration element and method of making
Inventor: BRAUN DAVID L
IPC: A62B18/02
Filed: 1988-09-14
Granted: 1993-10-12
Abstract: Abstract A filtering device, such as a respiratory mask, comprising porous, rigid or semi-rigid filtration element with inflow and outflow faces separated by a peripheral surface where the filtration element is supported by a resin mount, which may be in the form of the facepiece of a respiratory mask, that seals the surface without significantly penetrating beyond the surface pores of the filtration element.  The filtering device is made by inserting into an injection mold the filtration element and injecting resin into the flow channel of the mold at a pressure and temperature such that the resin does not significantly penetrate beyond the surface pores of the peripheral surface.      An inhalation plenum can be formed at the same time by inserting into the flow channel a thin layer of a second resin that does not melt at the pressure and temperature of the first resin.

Abstract: Abstract The invention relates to an indexable cutting insert for face milling of engine blocks of cast iron. The insert (10) has a free surface (16) and a clearance surface (13A) and a cutting edge extending peripherally about the insert. The corners of the insert have a relatively large radius and therefore the setting angle gets close to zero degrees during machining of the engine block when the insert gets close to the border line of the work piece. The free surface (16) and the clearance surface (13A) enclose an acute angle and therefore the insert has a positive cutting geometry. A land (18) is provided between the the free surface (16) and the cutting edge (19). The land (18) has a width increasing towards each insert corner.            (Fig. 3)

Title: Conduit isolation diaphragm assembly
Inventor: HUBER DONALD G
IPC: F16K17/40
Filed: 1989-05-24
Granted: 1993-06-08
Abstract: ABSTRACT        The present invention is an isolation diaphragm assembly designed to be installed in a standard tee, Y or coupling in a conduit to isolate one portion of the conduit from another.  In its initially installed condition, the isolation diaphragm assembly provides a seal for isolating portions of conduit systems for pressure testing.  Once the testing procedures are complete, the test diaphragm, being larger in diameter than the interior diameter of the conduit, is flexed into a saddle shape to permit its removal from a gasket and due to the decreased dimension, may then be drawn out of the conduit, leaving a fully unobstructed flow path.

Abstract: The present invention provides a temperature self-controlling heating composition containing crystalline resins, elastomers and electrically conductive particles, and an additional material to provide an affinity to the resins and the elastomers if they are not compatible.  The electrically conductive particles are stably dispersed in the medium of the resin and the elastomer, and agglomeration of the dispersed particles can be prevented, even if the temperature exceeds the melting point of the crystalline resin, because the apparent viscosity of the resin does not drop as a result of the network structure of the elastomers, so that the electrical resistance does not drop even at a high temperature.

Abstract: Abstract A separating device for quick mutual separation of objects and vehicles  especially air and space vehicles, comprises attaching elements, attached to the vehicle and the object, respectively, and arranged to interact separably in holding together the vehicle and the object. According to the invention, such a sepa-rating device is characterized primarily in that the first attach-ing element (1) comprises a casing with an internal first cylind-ric portion (2). In it a first piston (3) is arranged movable with slide fitting  so that the portion is separated into a first (4) and a second chamber (5). The first attaching element (1) shows a preferably conically generated first grip part (6). A second attaching element (8) has a second grip part (7) which can be separably attached to the first grip part (6) with a shrinking fit for frictional connection. A connecting channel (11, 12) con-nect the second chamber (5) with the surfaces (9, 10) of the grip parts. A source of pressure (14, 28) is arranged to increase essentially instantaneously the fluid pressure in the first chamber (4) so that the piston (3) will cause a liquid to sepa-rate the surfaces (9, 10) via the connecting channel (11, 12), releasing the grip parts (6, 7) from each other, for the sepa-ration of the object and the vehicle.
